[etherlab-users] Working counter of EL9820

[Hobin Yoon]

Hello,

I have a Beckhoff EL9820 slave board and its working counter seems to have a
problem. Its actual/expected working counter is 3/5. Is it a master's bug or
slave configuration's fault?

I am using ec_master version 1.4.0-rc3. I burnt the sii with the default
TwinCAT configuration file, which is, I believe, from
C:\TwinCAT\Io\EtherCAT\Beckhoff FB1XXX.xml.

# ethercat pdo
SM0: PhysAddr 0x0f02, DefaultSize    0, ControlRegister 0x44, Enable 9
  RxPdo 0x1a00 "Byte 0"
    Pdo entry 0x3101:01,  8 bit, "Output"
SM1: PhysAddr 0x0f03, DefaultSize    0, ControlRegister 0x44, Enable 1
  RxPdo 0x1a01 "Byte 1"
    Pdo entry 0x3101:02,  8 bit, "Output"
SM2: PhysAddr 0x1000, DefaultSize    0, ControlRegister 0x00, Enable 1
  TxPdo 0x1600 "Byte 0"
    Pdo entry 0x3001:01,  8 bit, "Input"
  TxPdo 0x1601 "Byte 1"
    Pdo entry 0x3001:02,  8 bit, "Input"

# ethercat slaves
0  0:0  PREOP  +  FB1111 16 Ch. Dig. In-/Output 2xMII

EtherCAT: Requesting master 0...
EtherCAT: Successfully requested master 0.
EtherCAT: Domain0: Logical address 0x00000000, 4 byte, expected working
counter 5.
EtherCAT:   Datagram domain0-0: Logical offset 0x00000000, 4 byte, type LRW.
EtherCAT: Master thread exited.
EtherCAT: Starting EtherCAT-OP thread.
EtherCAT: Domain 0: Working counter changed to 3/5.
EtherCAT: Slave states: OP.

Best regards,
